"Detection of faulty cells" - more of a joke, or does wrong !!

Have first new AA batteries charged by Euro Power because the thing meant by blinking, 2 of which were damaged. Was wondering - did they get out and again fooled - it's loaded. has made me ever suspicious. Then also quite new batteries from Camelion (all 2700mAh, all similarly discharged) - in all 4 the symbol has flashed empty - so errors. Then whole new AAA Duracell batteries inserted - flashes error.
Since just the latter, as well as the aforementioned and other (Hama, Sony, etc ..) batteries, which I have constantly in use, and were always loaded from the previous charger easily, 100% condition, I can of the " Error Detection "this charger would highly advise against! - It invites these cells simply not on - so this recognition for me is the knock-out criterion for this product and the reason why I have returned there again.
